In Jesus you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, having believed, you were sealed with the Holy Spirit of promise. Ephesians 1:13
God has put His royal seal on us: “Now He who establishes us with you in Christ and has anointed us is God, who also has sealed us and given us the Spirit in our hearts…” (2 Corinthians 1:21-22). Upon our conversion, we are sealed with the Holy Spirit.
The devil wants to come and destroy us because we are the children of God. He wants to wreak havoc in our lives. But when he sees our ID tag: “Owned by Jesus Christ. Sealed and insured by the Holy Spirit,” he backs off because he fears the One to whom we belong.
God’s Royal Seal is upon us, therefore we can be confident and fearless.
